BACKGROUND OF THE INVENTION 1. Fields of the Invention

The present invention relates to a trigger for a crossbow, and more particularly, to a trigger which restricts the trigger from being unintentionally pulled after the safety is released.

2. Descriptions of Related Art

The conventional crossbows generally include a barrel, a bow unit with a string, a string retention unit and a trigger. When in use, the string is cocked backward, and the arrow is positioned in the flight groove of the barrel. The string is restricted from being released until the user pulls the trigger to release the string, and the arrow in the flight groove is shot by the energy from the string.

In order to prevent the trigger from being unintentionally pulled to shoot the arrow out, a safety is used. The safety has to be released then the trigger can be pulled to shoot the arrow. One of the safety is disclosed in Taiwanese Patent Publication No. 1582373.

Nevertheless, in practical operation, after the safety is released, it is possible that the trigger is unintentionally pulled to shoot the arrow out due to unexpected impact to cause injury to people.

The present invention intends to provide a trigger of a crossbow and the trigger restricts the trigger from being unintentionally pulled after the safety is released.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 4, the first embodiment of the trigger of the present invention comprises a trigger guard 10 which is a rectangular frame with an inner periphery 11. The trigger guard 10 is connected to a crossbow 1. A trigger 20 is pivotably located within the trigger guard 10 and includes a front face 21 and a rear face 22. A space 23 is defined in the rear face 22 of the trigger 20. A switch member 30 includes a body portion 34, and an operation section 31 and a contact section 32 are respectively formed on two ends of the body portion 34. The body portion 34 is pivotably connected in the space 23. The operation section 31 and the contact section 32 of the switch member 30 are pivotable relative to the trigger 20.

A resilient member “A” is located in the space 23 and biased between the contact section 32 and the inner end of the space 23. The contact section 32 is pushed by the resilient member “A” to contact the inner periphery 11 of the trigger guard 10 to restrict the trigger 20 from being pulled. In other words, the trigger 20 is prevented from being pulled unintentionally even if the safety is released. When the operation section 31 is pulled, the switch member 30 is pivoted, and the contact section 32 compresses the resilient member “A”, so that the contact section 32 is moved away from the inner periphery 11 of the trigger guard 10, and then the trigger 20 is able to be pulled.

The trigger 20 includes a bottom face 24 which is formed with the front face 21 and the rear face 22. The operation section 31 includes a press face 311 and two lateral faces 312 that formed on two sides of the press face 311. The press face 311 of the operation section 31 and the front face 21 of the trigger 20 both face the same direction. The body portion 34 is narrower than the operation section 31, the body portion 34 extends from the top end of the operation section 31 so as to form two top faces 313 between which the body portion 34 extends. When the operation section 31 is pulled, the two top faces 313 of the operation section 31 contact the bottom face 24 of the trigger 20 to pivot the trigger 20 as shown in FIGS. 3 and 4.

The space 23 includes a first recess 234 defined in the inner end 231 thereof as shown in FIG. 2. The switch member 30 includes a second recess 33 which is located corresponding to the first recess 234. The resilient member “A” is a compression spring, and two ends of the resilient member “A” are respectively positioned in the first and second recesses 234, 33.

The present invention discloses a second embodiment of the trigger of a crossbow 1 as shown in FIGS. 5 to 8, and comprises a trigger guard 10 and a trigger 20. The trigger guard 10 includes an inner periphery 11, and the trigger 20 is pivotably located within the trigger guard 10. The trigger 20 includes a front face 21 and a rear face 22, wherein a space 23 is defined in the rear face 22 of the trigger 20. The trigger 20 includes a slot 23 defined through the lower portion thereof so as to form two extensions 25 with the slot 23 formed therebetween. The slot 23 communicates with the space 23. A switch member 30 includes a body portion 34, and an operation section 31 and a contact section 32 are respectively formed on two ends of the body portion 34. The body portion 34 is pivotably connected in the space 23. The switch member 30 is pivotable relative to the trigger 20. The operation section 31 is located between the two extensions 25, and extends beyond the slot 233.

A resilient member “A” is located in the space 23 and biased between the contact section 32 and the inner end of the space 23 as shown in FIG. 7. The contact section 32 is pushed by the resilient member “A” to contact the inner periphery 11 of the trigger guard 10 to restrict the trigger 20 from being pulled as shown in FIG. 8. When the operation section 31 is pulled, the switch member 30 is pivoted, and the contact section 32 compresses the resilient member “A”. The contact section 32 is moved away from the inner periphery 11 of the trigger guard 10 such that the trigger 20 is able to be pulled.

As shown in FIGS. 5 to 8, the space 23 includes a first recess 234 defined in the inner end 231 thereof. The switch member 30 includes a second recess 33 which is located corresponding to the first recess 234. The resilient member “A” is a compression spring, and two ends of the resilient member “A” are respectively positioned in the first and second recesses 234, 33.

The present invention discloses a third embodiment of the trigger of a crossbow 1 as shown in FIGS. 9 to 12, and comprises a trigger guard 10 and a trigger 20. The trigger guard 10 includes an inner periphery 11, and the trigger 20 is pivotably located within the trigger guard 10. The trigger 20 includes a front face 21 and a rear face 22. A space 23 is defined in the rear face 22 of the trigger 20. The trigger 20 includes a slot 23 defined through the lower portion thereof so as to form two extensions 25 with the slot 23 formed therebetween. The slot 23 communicates with the space 23. A switch member 30 includes an operation section 31, a contact section 32, a body portion 34 and a plate 35. The plate 35 is made of resilient material and can be slightly deformed. The operation section 31 and the contact section 32 are respectively formed on two ends of the body portion 34. The body portion 34 is pivotably connected in the space 23. The switch member 30 is pivotable relative to the trigger 20. The operation section 31 is located between the two extensions 25, and extends beyond the slot 233 so as to be operated by the users.

The plate 35 extends from the switch member 30 and is located between the contact section 32 and the body portion 34. As shown in FIG. 11, the plate 35 extends toward the trigger 20 and resiliently contacts the inner periphery 11 of the trigger guard 10 so as to restrict the trigger 20 from being pulled. When the operation section 31 is pulled, as shown by the arrow head in FIG. 12, the switch member 30 is pivoted, and the contact section 32 compresses the plate 35, the contact section 32 is moved away from the inner periphery 11 of the trigger guard 10 such that the trigger 20 is able to be pulled.

It is noted that an angle θ is formed between the plate 35 and the contact section 32. The plate 35 contacts the inner bottom 231 of the space 23. The plate 35 resiliently pushes and pivots the switch member 30, so that the contact section 32 contacts the inner periphery 11 of the trigger guard 10 to restrict the trigger 20 from being pulled. When the operation section 31 is pulled and the switch member 30 is pivoted, the contact section 32 is moved to narrow the angle θ, so that the contact section 32 is separated from the inner periphery 11 of the trigger guard 10 to release the trigger 20.

The present invention provides the switch member 30 in the space 23 of the trigger 20, and the resilient member “A”/the plate 35 located between the trigger 20 and the switch member 30, to ensure that the trigger 20 is not unintentionally operated to shoot arrow to cause injury to people.

In other words, the resilient member “A”/the plate 35 pushes the switch member 30 to make the contact section 32 contact the inner periphery 11 of the trigger guard 10, so as to restrict the trigger 20 from being pulled.

The crossbow 1 provides a further safety feature to restrict the operation of the trigger 20 after the safety is released, so that the trigger 20 is not pulled due to impact.
